Expanded Housing Option (EHO) Development offers an alternative on single-family residential lots that allows for the construction of duplexes, townhouses, and multifamily buildings that meet the design standards in Arlington County Zoning Ordinance (ACZO) ยง10.4 Expanded Housing Option Development.
